It sounds like a dream. Fill out a perfect March Madness bracket, win $1 billion.

Although it seems like something that couldn’t be real, Warren Buffett has made it into a reality. Sort of. That’s right, the Oracle of Omaha is partnering with Quicken Loans to give away $1 billion to anyone that fills out a perfect bracket this March. The offer is really on the table from Buffett, but as with most of his business ventures, the risk is very calculated.

“It is our mission to create amazing experiences for our clients. This contest, with the possibility of creating a billionaire, definitely fits that bill,” said President of Quicken Loans Jay Farner. We’ve seen a lot of contests offering a million dollars for putting together a good bracket, which got us thinking, what is the perfect bracket worth? We decided a billion dollars seems right for such an impressive feat.”

Why did they decide on $1 billion as the prize? Because it’s a feat that’s nearly impossible to pull off. The odds of filling out a perfect bracket? 1 in 9.2 quintillion. So clearly, this is a publicity stunt.

But in defense of Buffett and Quicken Loans, they are giving out $100,000 each to the top 20 brackets and they’re also donating $1 million to charity. So there will be some actual winners.

However, for the most part, this is just something to get people talking. At the same time, fans have nothing to lose by filling out a bracket. It’s free and there’s no harm in getting in the running for a cool billion.
